Hi Wombo. I honestly have done no more research into this for ages. All the info I have is that Hannah was born in 1849 in Newcastle-upon-Tyne, Northumberland. Robert was born 1853 in Scarcroft, Yorkshire and died in Victoria, Australia in 1941. If there are any questions you need answering about their ancestors, please ask. The parents of Hannah and Robert were Frederick Charles Tyzack, born 1826 and Eliza Margerrison, also born 1826. Frederick, as far as I can tell was the illegitimate son of a Mary Ann Tyzack.
